The British Standards Institution’s (BSI) document “Guide to good practice in commissioning accessible websites” is now available free of charge from the Disability Rights Commission.

The document is "for those responsible for commissioning or maintaining public-facing websites and web-based services" , which I guess includes all web designers in the UK. Previously we had to stump up £30 for this which was in hard copy only, but now it is here in .doc or pdf format - no html version and there are the usual BSI/Government terms attached!
